Although it's a pretty good idea, it could be better to have some more gameplay to make the player feel the load of responsibility.
Also, I think that you should not refer to real politics here. You could simply write “Enemy Forces” or come up with an abstract, fictional name for the country (like in“Papers, Please”) instead of mentioning the real one.
Since I myself am Russian, I did not like that my country was demonized. I think it's not a good idea to bring bad thoughts about ordinary foreigners to the player.
